Depending on the specific polymer matrix and final application, the standard defines distinct pathways—referred to as procedures—for handling the test specimens. Procedure Name Environmental Matrix Exposure Duration Primary Application 23 ± 2°C, 50 ± 5% Relative Humidity Minimum of 40 hours Standard laboratory baseline for general-purpose plastics. Procedure B 50 ± 2°C, Dry Atmosphere (Desiccation) Elevated temperature drying to eliminate residual moisture. Procedure C Liquid Immersion in Distilled Water Varied (typically 24–48 hours) Marine or fluid-contact simulations. Procedure D 35 ± 2°C, 90–95% Relative Humidity
